I did some rendering at the weekend, started at 4pm Saturday, and with minimal pausing it was completed 21hrs later!!
I did 3 complex renders, the first which was a test run and still needs to be redone (6-12hr job maybe) and the other 2 were alternative scenes.
been meaning to show the Merc guys this all weekend but havent uploaded it for them, so once i've got them online i'll stick a link in here for them
